If you use an acoustic coupler to connect your telephone for recording, you can record TTY and voice into a single announcement. In this case, when you press 1 to record, you can type the TTY message, then immediately pick up the handset to record the voice message. For this type of recording, digital telephones also offer the option to press # to complete the recording, which eliminates any extraneous noise at the end of the recording. Unfortunately, using this method for combined TTY and voice recordings is likely to create extraneous noise in the middle of your announcements.
